Description

Transformer DC resistance is a must-test item for semi-finished products, finished products factory test, installation, overhaul, change of tap changer, handover test and preventive test of power sector in transformer manufacturing. It can check the welding quality of the winding joint and whether the winding is short-circuited between turns. It can check whether the contact of each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the lead wire is broken, and the multi-strand wires are wound in parallel. Whether there is a stock break, etc.

Feature

•  The output current of the instrument is large and the voltage is high.

• Dual-channel measurement, measuring two resistance values at the same time.
  

•  It has perfect protection circuit and strong reliability.
  

•  The horizontal structure is convenient for on-site operation of the transformer factory.
  

•  It has an audible discharge alarm, and the discharge indication is clear to reduce misoperation.
